This invention relates to vault protection devices intended to supplement the protection aiiorded by; alarm systems and time locks by delayingan attemptat forcible en- .5 try either bysupplemental locking means actuated by an unauthorized disturbance of the regular lock or by discharging a noxious gas into the vault by similar means. It is, accordingly, a vprincipal object ofthe prescut invention to -provide an improved opcrating or restraining mechanism -for a relock or gas bomb, the disturbance or injury of WlllCllF-Wlll release .orf actuai'e the -protec tive device. 'Thedesired result is preferably obtained by forming a tensioned network of Wires over the more vulnerable portions of a, closure and so-connecting-this :network of tensioned Wires to the actual bomb or relocking mechanism as to -restrain such mechanisms from operation.
